#' Varieties of Democracy (V-Dem) is a new approach to conceptualizing
#' and measuring democracy. We provide a multidimensional and disaggregated
#' dataset that reflects the complexity of the concept of democracy as a
#' system of rule that goes beyond the simple presence of elections.
#' The V-Dem project distinguishes between five high-level principles of
#' democracy: electoral, liberal, participatory, deliberative, and
#' egalitarian, and collects data to measure these principles.
#' With five Principal Investigators (PIs), thirty-nine Project Managers
#' (PMs) with special responsibility for issue areas,
#' more than thirty Regional Managers (RMs),
#' 134 Country Coordinators (CCs), Research Assistants,
#' and over 4,000 Country Experts (CEs). The V-Dem project is one
#' of the largest social science data collection projects
#' focusing on research. The Headquarters is based at the
#' V-Dem Institute, the Department of Political Science at the
#' University of Gothenburg, Sweden. The most recent data set (v15)
#' covers 202 countries from 1789-2024 and includes 500+ indicators,
#' 81 indices and 5 high-level indices.
